Missing title bar in custom panels

Hi everyone I’m pretty new to home assistant development.
I’m trying to create a custom panel with an iframe inside; I managed to make it work but my panel is missing the top bar and I can’t find how to enable it.
This isn’t much a concerne on desktop but on mobile I can’t access the panels’ hamburger menù because it’s inside the top bar.

This my entry for the custom panel in the configuration.yaml file:


  - name: iframe-fullscreen
    module_url: "/local/iframe-fullscreen.js"
    sidebar_title: 'Socket settings'
      url: "/local/test_panel/test.html"
